You should read a tutorial about "how to ask questions". Giving more information (like showing the algs that use those notations) would help figuring out what your problem is.

How exactly didn't that help? Don't you understand what "Us = Ds’ = U D’" means, or do the algs not work with that definition?

right clockwise 90 deg, left 180 deg, down face (the "bottom of the cube) counter-clockwise 90 deg, back face (opposite front) 90 degrees counter-clockwise), down face 90 degrees clockwise, back face 90 degrees clockwise, left face 90 degrees clockwise, back face 90 degrees counter-clockwise, left face and middle slice 90 degrees clockwise.

I think...

There are a few different notations floating around. We all pretty much use the same notation on this forum, but what you've written most likely wrong. The generally accepted notation is explained pretty clearly here: http://www.nascarjon.us/notation.html

R means turn the right side face clockwise. r means turn the right side face and the center set of cubes as a unit clockwise, sometimes called a "double face turn" or "whole turn" and sometimes notated Fw, but not here. Ls means "left slice" which

I'd be very surprised if you came across an algorithm that included only whole turns, more than likely either the algorithm was written wrong or you didn't preserve the case. Especially since it doesn't do anything useful to the cube.

Also it helps if you type the cube notation in capital letters as it should be for all the letters except like s or w or if its a double layer turn.
An how did Johannes' link not help? The first site on the google search had all the notation you were asking for... but notation like that is not used very often. I don't think slice turns like that are very fingertrick friendly.

I don't know, I use what's really a Ds in my Z-perm. I notate it as a U' D, but execute it as a Ds. In the same alg I end up doing a U D, which I execute as a Da, my fingers just happen to be right there and it's completely finger friendly. (All that's precluded by the assumption that I've really understood the Ds and Da correctly). :)
